The WDT3000 has a highly configurable and structured Job Management software interface for applications such as job dispatch and GPS location acquisition and status reporting. Some interface fields may be configured ‘over-the-air’. The on-board GPS management system can set location acquisition and data transmission parameters by time or distance, or by stopped/moving events. There is also an internal geo-fencing capability for automatic status updating.
